Various Topological Poly(tert‐butyl acrylate)s and Their Impacts on Thermal and Solution Properties

Macromolecular Rapid Communications, Volume 46, Issue 15, August 4, 2025.
Different polymer topologies including linear, tetra‐arm, cyclic, and 8‐shaped polymers are synthesized using a combination of ARGET ATRP and click reactions. The polymers are designed to have similar molar masses for a comprehensive comparison. The thermal and solution properties of these topologically diverse polymers are thoroughly investigated to ...

Thermally Activated Swelling and Wetting Transition of Frozen Polymer Brushes:a New Concept for Surface Functionalization

Advanced Materials, Volume 37, Issue 26, July 3, 2025.
A novel approach is introduced that leverages polymer phase transitions to modulate brush behavior. The oleophilic bottle brush system exhibits two distinct melting transitions—bulk and surface—enabling a two‐stage swelling and wetting transition.

Functionalized Antifouling Polymer Brushes for Biospecific Surfaces

Advanced Materials Interfaces, Volume 12, Issue 14, July 25, 2025.
Modern biosensors offer high sensitivity but often struggle with long‐term stability and selectivity for specific targets. Antifouling polymer brushes help enhance both stability and selectivity. In this review, we compare recent antifouling coatings, their design parameters, and how they are integrated with biorecognition elements for improved ...

Composition and Microstructure of Biocompatible and pH-Sensitive Copolymers Prepared by a Free Solvent ARGET ATRP

, 2020
Controlled/living radical polymerizations enable the synthesis of functional polymers with well-defined compositions and architectures. In this paper, we propose the usage of the ARGET ATRP technique to produce copolymers of MMA and DMAEMA.

Improved Dewatering of Mature Fine Tailings Using High Molecular Weight Polyacrylamide Grafted From an Activated Carbon Surface by Surface‐Initiated ATRP

Journal of Applied Polymer Science, Volume 142, Issue 22, June 10, 2025.
Efforts to address mature fine tailings in oil sand processing are advanced through the grafting of high molecular weight polyacrylamide onto activated carbon via surface‐initiated ATRP. Two grafting methods are compared, demonstrating improved dewatering performance with solids content increasing up to 50 wt%, offering a sustainable solution for ...

Basicity Can Choregraph Regeneration in Homogeneous ARGET ATRP of Styrene

, 2022
There are two drawbacks in the use of H2AA when polymerizing a hydrophobic monomer such as styrene. First, the low solubility of the reducing agent in non-aqueous solvents. Second, the reduction kinetic rate constant of the catalyst by H2AA is around two-orders of magnitude lower than that of ascorbate (HAA–).
